I already listened to F# A#, I just didn't want to include GY!BE twice, and I am going to listen to This is Our Punk Rock... by A Silver Mount Zion sometime soon. What album by Gregor Samsa should I check out?

Yndi, Sigur Ros, and Jaga Jazzist fo' sho'. I'm just getting into Gregor Samsa and really digging it. For more recent stuff, check out the Gifts from Enola/You May Die in the Desert split LP, Ef's I Am Responsible, and Daturah's Reverie.

If you like 2, I recommend checking out Broken Social Scene, they arn't exactly post-rock, but they share a similar sound, and they're amazing - one of Do Make Say Think's guitarists is a touring live guitarist for them atm, go figure.
